FILLINGJVIACHINE.

To alf whom it may concern:

Be it known that I, LUDWIG JAEGER, a subject of the Emperor of Germany, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Filling-lvfachines, of which the following is a specification.

In filling bottles with beer and other charged liquids at the present time provision is sometimes made for retarding the escape of air or gas from the bottle during the filling operation to regulate the inflow of beer, but as far as I am aware, this retardation of the escape of air or gas has been uniform during the filling operation and no attempt has been made to regulate or control the escape of air or gas as the hydrostatic head of the beer decreases during the filling operation. IVhen this retardation is uniform the velocity of the beer will vary with the variation in the hydrostatic head and this may cause an agitation of the beer and produce foaming. But if the escape of air or gas is regulated according to the change constantly taking place in the hydrostatic head during the filling operation the velocity of the beer fiowing into the bottle will be maintained constant and agitation and foaming entirely avoided.

It is my object to avoid the disadvantages of the present methods of filling` bottles with beer and other charged liquids by maintaining the velocity of the liquid flowing into the bottle constant throughout the filling operation and avoiding all changes in velocity ordinarily due to variations in the hydrostatic head of the liquid.

Another object of the invention is to provide a filling machine of large capacity and which can be operated rapidly without causing the liquid to foam. And a further obliect is to provide means for automatically and positively regulating and controlling the escape of air or gas from the bottle during the filling operation, not only to retard the escape but also to compensate for the loss in hydrostatic head at the same time and thus maintain a constant velocity for the inflowing liquid.

As the invention is especially important in connection with filling beer I will hereafter refer to this particular use, but it will be understood of course that the invention presents the same advantages in filling other charged liquids.

Serial No. 395,472.

In the accompanying drawings illustrating one embodiment of the invention Figures l and 2 are sectional views showing much of a filling machine as is necessary to understand the invention, Fig. 2 showing the lid of the tank illustrated in Fig. l and adapted to be secured, with the parts carried thereby, on said tank.

Referring to the drawings 5 is a tank of suitable character provided with a partition 6 which does not extend to the top of the tank and which divides the tank into a beer chamber 7 and a water chamber 8. A constant head of beer is maintained in the chamber 7. The tank may be circular in form and provided with a plurality of filling mechanisms to all of which the beer chamber 7 and the water chamber 8 are common. For the present purpose it is only necessary to show and describe a machine having one filling mechanism. A filling tube 9 is secured in a body 10,'the latter having a bore 1l, to form a communication between the tube and tank, and a valve seat l2 at the upper end of the bore. A head 13 is arranged to slide on the filling tube and it is provided with a seat lll to receive the upper end of the guide bell l5 for centering the bottle on the filling tube. This bell is slidable on the filling tube and a collar 1G prevents the bell from slipping off the lling tube. The bell and head have air or gas passages 17, 1S, the latter communicating with an air tube 19 which is secured in the head and projects upward through an opening 20 in the body 12 into the beer chamber. Fig. l shows the bell pushed up by a bottle and seated against the head preparatory to moving the head for a purpose hereafter described. A spring 2l on the filling tube between the body and head will return the head and the parts connected therewith to lowered position, as shown in Fig. l, when the pressure of the bottle is withdrawn and at the same time the bell will slide by gravity to the lower end of the filling tube.

A beer valve 22 is normally seated on the seat l2 to close the filling tube and this valve is carried by a rod 23 which projects through a bracket 24 fastened on the air tube within the beer chamber. A collar 25 is fastened on the rod 23 above the bracket 24; so that the bracket will engage with said collar when the air tube has been raised sufficiently and unseat the beer valve.

rllhe air tube 19 is made in two sect-ions 197 19, the upper section 19 being carried on the lid 26 of the tank, this lid being secured tightly on the tank by bolts 2T and nuts 28. r1`he air tube is made in two sections so that the lid can be removed trom the tank when desired without requiring the disconnection of any ot the parts. A bracket 29 is secured on the section 19 of the air tube within the beer chamber and this bracket terms a guide for the rod 23. A collar 30 is fastened on the rod 23 and a spring 31 is arranged on said rod between the bracket 29 and collar 30 to return the valve 22 against its seat. The section 19 ot the air tube is provided at its upper end with a seat- 32 against which the lower end of the section 19 normally seats when the tank lid is lon and a guide 33 having a conical opening 34 is secured to the section 19 of the air tube above the seat 32 to guide the section 19 of the air tube into position against the said seat.

A casing 35 for each illing valve is mounted on the lid 26 of the tank and this casing is provided with a water chamber 36 and another chamber 37 The section 19 of the air tube is arranged within the chamber 37 and it carries, below its upper end, an air valve 38 which seats against a seat 39 on a plug 40 secured within said chamber. rlhis plug has an air passage 41 which is closed when the air valve is seated. The upper end ot the air tube section 19 projects into an enlarged sleeve 42 which is suspended from a valve casing 43 within the upper end of the chamber 37. A spring 44 is arranged on the sleeve 42A and bears against the casing 43 and the air valve 38 to hold said valve normally against its seat. The casing 43 has a bore 45 which communicates with the sleeve 42 and is located above the upper end of the air tube section 19 and a valve 46 is arranged within this casing and seats against a seat 47 at the upper end of said bore. The stem 48 of valve 46 is guided in a screw plug 49 in the upper end ot the casing and a spring 50 on said stem holds the valve 46 normally against its seat. An air passage 51 in the valve casing 43 forms a communication between the valve chamber above the air valve and an air passage 53 at the top of the casing A port 54 in the valve casing 43 forms a communication between the valve chamber 55 and an air pipe 56 which extends down adjacent to the bottom of the water chamber 36. A water pipe 57 is secured in t-he bottom of the water chamber 36 and extends down adjacent to the bottom of the water chamber 8 in the tank. A supplemental water pipe 58 is secured in the bottom of the water chamber 36 and extends nearly to the top thereof and adjacentto the bottom of the water chamber 8 in the tank. A plug 59 having a valve opening 60 and valve seat 61 is secured in the casing 35 at the top Ot' the water chamber 36 and a ball valve 62 is held in place at the top or" said water chamber 36 by arms 63 to engage said seat. r1`he air passage 53 communicates through said valve opening 60 with the top of the water chamber 36.

In practice the water chamber 8 may be i'illed nearly to the top with water and when the beer is introduced to the beer chamber under pressure the pressure will torce the water up through the pipes 5T and 58 into the chamber 36 until the ball 62 is seated. Then a bottle pushes the guide bell 15 up against the head 13 and moves the head up on the filling tube7 the air tube carried by the head will rise and unseat the air valve 38, thereby establishing communication between the beer chamber and the bottle through the chamber 3T, passage 41,4 chamber 527 sleeve 42, air tube 19 and the passages 18 and 1T in the head and guide bell to permit an equalization of pressure in the bottle and beer chamber before the beer valve is opened. At the same time the pressure in passages 51 and 53 is equalized with the pressure in the tank so that the water will begin to flow from the chamber 36 into the chamber 8, the ball valve 62 opening as the water escapes from chamber 36. Only a comparatively small and immaterial quantity of water will flow out of chamber 36 bet'ore the beer valve 22 is opened for it will be understood that the beer valve is opened very quickly after the air valve 38 is opened. lVhen the bracket 24 engages the collar 25 on the continued upward movement of the head the beer valve 22 will be opened to permit the beer to iiow from the beer chamber into the bottle. At the same time a valve 64 on the air tube seats against the lower end 42 of the sleeve 42 and the upper end of the air tube engages and unseats the valve 46. rlhen the air escaping from the bottle passes through lateral ports 65 in the upper end of t-he air tube into the chamber and through the port 54 into the air pipe 5 The air escapes trom the lower end ot the air pipe 56 and passes up through the water. in the chamber 36 in the form ot bubbles. The water in chamber 36 flows through the pipe 57 into the chamber 8 by gravity only; tor when valve 38 is opened the pressure in the bottle is equalized with the pressure in the beer chamber and in the water chamber 8. As just mentioned the water is caused to flow from the chamber 36 to the chamber 8 by gravity. then valve 64 is seated the air escaping from the bottle works against the head of water in the chamber 36.

The water chamber 8 may be called the storage chamber and it can be made in any suitable shape. The water chamber 36 may be called the gravity chamber and it is preferably tapered or contracted at its lower end to correspond in a general way with the taper shape of a bottle in inverted position. The hydrostatic head of the beer changes gradually as the bottle is filled and hence it becomes necessary to regulate the flow of water from the chamber 36 to the chamber 8 in accordance with the variation in hydrostatic head of the beer in order to maintain the flow of beer at a constant velocity. It is for this reason that l make the gravity chamber in tapered forni corresponding somewhat to an inverted bottle so that the velocity of the water flowing from the gravity chamber to the storage chamber will decrease to correspond with the loss of hydrostatic head.

By the time the bottle has been filled the gravity chamber will be empty and when the bottle is lowered the spring 21 will push the head 13 down to its lowered position, carrying with it the air tube, and the liquid valve will close by gravity and under influence of the spring 31. At the same time the valves 46 and 38 will be carried against their seats and the valve chamber 52 will be open to the atmosphere through the air tube and the air passages 18 and 17. At this time the gravity chamber 36 is also opened to the atmosphere through the valve opening 60, the passages 53 and 51, the valve chamber 52, the air tube and the air passages 18 and 17. Then the air pressure in the beer chamber and water storage chainber 8 forces the water up through the pipes 57 and 5S into the gravity chamber until the valve G2 is carried against its seat. The two pipes 57 and 58 are provided in order to return the water to the gravity chamber quickly so that the filling operation may be resumed at once.

t will be observed that the air which is forced out of the bottle during the filling operation escapes from the water pipe 5G at the bottom of the gravity chamber and rises in the form of bubbles through the water to the top of the gravity chamber. rlhe water retards the escape of air from the bottle and causes the air in the bottle to form, in effect, a cushion for the inflowing beer by providing a somewhat greater pressure in the bottle than in the tank and preventing the discharge of beer in the bottle at a pressure which would tend to produce foaming. The water in the gravity chamber not only forms a check to retard the escape of air from the bottle as described but also provides for automatically varying the retardation of the escape of air from the bottle as the hydrostatic head of the beer changes to provide a constant velocity for thobeer,

1t will be readily understood that the resistance caused by the water to the escape of the air in the gravity chamber is :reduced as the water fiows out of the chamber', and as the beer flows into the bottle to reduce the hydrostatic head.
